WINDOW SCREEN.

Application filed `Augusty 24, 1925. Serial No. 52,153.

This invention i'elates to screens andV particularly to the frames thereof, as applied to window and like openings through which it isy desirable to allow air to Vpass but prevent the intrusion of insects, etc.

f One of the objects of tliefinvention is to provide a sectional. screen having automaticl means for length extension to suit require-y ments, and which is generally applicable to windows of any ordinary type. g

A further feature is in theprovision of telescopic stay rods and j guides combined with stops limiting the ultimate contraction' and expansion of the sections, and guide the `sections at all times in parallel relation.

Another aim is to produce a screen of unusually strong construction, in which the: spring actuatingrmeans is concealed andV protected from injury, and which presentsy a neat and attractive appearance.

lThese and other important objects are achieved inthe present invention by the' novel and practical construction'and combination of elements hereinafter reveal-ed and illustrated in the associated drawing, constituting a component vpart of this disclosure, Yand in which Y Fig. 1 is a partial front eleva-tional view of a conventional type `of window, showing the application of an embodiment of the in* vention. Y

ably engaged, the 'same being shown. raised The 'screen frame as shown in Figs. lto

i 3 inclusive is composed oftwo normally 'upright rectangular bars 14 and 15, iitted toA engage in the groovespof the easements onopposite sides of the window, their width being such as to extend inwardly towards'each other, as shown in Fig. 1. p

`Each of the bars contain vin their' inner faces longitudinal grooves 16 and 17v offset from each other, one being close to the rear surface and the other near the front. y

Rigidly fixed in these grooves are the re-` duced ends of cross rails 18fand 19, arranged in pairs at the topfand bottom of the frame,

these cross rails carrying, near their innerends, vertical metal strips 20 and 21 formed:V

into channel shaped vcross sections connecting the upper and lower rails and receptive of Vthe edges-of screen sheets 22 and 23.

The horizontal edges of these screensheets are held in grooves 24 and 25 in the adjacent Y sides of the rails 18 and 19, and the oppo site ends of the screensheets'aresecured in the grooves 16 and 17 of the bars 14 and 15, thus constituting twoindependent screen sections.

Formed in theadjacent faces of both pairs of rails 18 and 19 are registering undercut recesses 26 and 27, extending throughout their length and at the ends of the rails are p tennoned blocks' 28 and 29 fixed therein toy slide freely in the opposite4 recesses, thus 'Y guiding and confining the two. screen secpermitting relative` longi- Fixed on the bars 14 and 15, on opposite ing telescopically received in tubes 32 and 33,

lsimilarlyengaged on the opposite *sides of the bars 14 and 15, and'held-to the rails 18 and 19- by eyes 34 secured therein.

The tubes 32 and 33 are further heldin place by pairs of clips 35 `coiled therearound and extending from loops 36 enveloping the outer side and edge surfaces Vof each pair of rails 18 andA 19 at the tops and bottoms o the combined frames. f

Fixed in the tenon blocks 28 are eyes 37 engaging one of the ends ofhelically coiled tension springs 38, disposed in the recesses 26 and 27, thesesprings being secured at their opposite ends by pins 39 and having the function of drawing the screen sections apart, acting to press the bars la and l5, into rm engagement Within the Window traine recesses.

A finger grip 40 is tix-ed on one of the vertical bars, as 15, by which the screen sections may be conveniently caused to Vslide when inserting or removing the saine.

.Loosely engaged on one of the lower telcscopic tubes is a clip Ail carrying a perilor'ated plate 42 which may be tasten-ed to the sillof the Window, thus anchoring the screen in position and acting as a reentorceinent for .the saine.

It is to be noted that the rods and tubes olier an opportunity to conveniently'display curtains or like draperies it desired in addi`H tion to their reentorcing functions.

In the modification shown in Figs. and 5, a siinple type oft slidable sectional' screen is disclosed, the saine embodying the chai'- acteristic `features previously described. In this construction a Apair ol' b rs 50 and 51 contain longitudinal grooves in their inner faces, disposed respectively near their rear and front surtacesand fined in the ends of these grooves are the ends ot rails 52 and 53. U

rPhe rails are engaged, near their opposite free ends, by inetal channel connecting strips d vand 55 adapted toreceiye the inner end edges ot screen sheets 56 and 57, the other edges of which are iiXed in grooves in the Y rails 52r and 53, and bars 50 and 51.

Y Both paii's of rails 52 and 58 are provided With undercut Vregistering longitudinal re'- cesses 'and 59 in which are slidably received blocks 60, secured at the ends -o't the opposed rails, these blocks acting as gui-des and to confine the pair of trarne sect-ions Y against other thanl lineal movement.

As a further securing ineans, screws (31 are passedthrough elongated slots 62 .and 53 Vin the rails 52 and :53, the screws engaging the blocks G0,v and, as shown, constitute holding ineans for coiled tension springs 64, disposed Vin the recesses 58 and 59, and act to pull the.

traine sections outwardly in the manner .before-described. p

VIn the preferred embodiment or the inven-` tion., shown in'ldigs. 6 to 9 inclusive, Ya pair of upright bars and 7l fixed at vtneii ends in inetal channels 72 and 73 in which they are secured by fastening rneans 7 et.

Fixed in the channels, on opposite sides, arer strips 75 and 76 containing grooves to receive the upper and lower edges of screen sheets 77 and 7 8, their outer edges beingl set in slots in the bars 70 and 71 and their .inner edges fixed in channels 79 and S0 ens tending` from the adjacent ends ot the strips 75 and 76. Y

Formed in the horizontal eleinents 72 and 73 oi' the frames, are central longitudinal slots 8l and 82 and passing through these slots are bolts S3, their bodies passing through close fitting openings in the inating traine inenibers and beine enO'aOed b f nuts,V

It Will be understood that the channels 7 3 are sui'hczientlyA :larger in cross` section than the chambers so to receive the sanie'ielfe- Froin the foregoing it Will Vbe seen that siinple devicesy 'tor the purpose stated hr e been disclosed Yin their preferred embodiinents, but it Will-lie manifest that rminor changes inay be niade, not involvingl the ener.
